Application filed June 20, 1923. Serial No. $8,720

To all whom it may comer a:

Be it known that I, Gusrr a eitizen'of the UnitedStates, residing atGridley, county of Butte, "State of California, have invented'cert'aid'new and useful mo iles; and I do declare the following to be afull, clear, and exact description of the same, referencebeing had tothe accompanying' drawings, and to the characters of referencemarkedthereon, which form a part of this application.

1 means forpreventing skidding of motor'vehiclesLon wet pavements, suchas frequently -principal object of my invention therefore s to providemeans for sprinkling sand onto the tires of the vehicle this materialhav ng well-known non-slippage properties when used sparsely, controlmeans for the sprin;

kling of the sand being provided arranged tabsl actuated onlywhen'thebrakesare appl1e' a a I have also arranged for the-readydisconnection of the sand control means from the brake applying means,when it is unnecessary to use the same, as 1n dr weather, when tosprinkle sand onto the tires would be a mere waste of the material. Afurther object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedingly effective for the purposesfor which it is designed.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of v thefollowing specification and claims.

In the drawings similar characters of ref- 'erence indicatecorresponding: parts in the several views. i

In carrying out my invention it will be evident that different makes ofcars will necessitate somewhat different arrangement of the variousparts, and the accompanying drawings of course only show the arrangementon a certain make of car, and even on such car, the arrangement may bevaried.

Fig. 1 is a side outline of an automobile showing my sanding device asapplied thereto. I

Fig. 2 is a top plan view of the same.

" EM} Johnson,

This invention relates to-"an improved Fig. 3 is a fragmentary view of abrake pedal showing the connection of-th'e'sand' control member thereto.

Fig- 4 is a fragmentary endfview of a '-sand-valve actuating rod and itsconnected Im rovements in'Sanding Devices for Autoparts. I

Referring now more particularlyto the characters of reference on the'drawings, the numeral 1 denotes the frames of the vehicle, 2 the body,'3 and 4 the front and rear the brake pedal. 4

My invention'comprises preferably an in-' air ofsand' containers 7 and8,

dependent one somew ere, near and above the front wheels, as shownunderthe-hood, and the other similarly located withrespect to the I rearwheels, as at-the back of the dicated. Removable filler caps 9 arerovided for the containeraj-so that they may easily filled whennecessaryz Sand pi es;1 0 extend down from the containers an -throughthefenders- 5 so as to wdllslchlarge"onto the-tread of the tires of the-w ee s.

odyas inwheels, 5 the fendersor mudguards, and 6 Suitable controlass -11m placed in the .pipes adjacent their lower' ends, these valves beingautomatically closed by springs Means to positivelyopen all ..thesevalves 7 in unison with the depression of the pedal 6 1s rovided asfollows: 7 4 ournaled on' the frames 1 adjacentthepedal 6 and extendingtransversely of the vehicle is a rod or shaft 13, having at its outerends vertical arms 14, extending on both sides of the shaft.

Pull wires or cords 15 extend from the outer ends of these arms to thevalves 11, said wires being preferably enclosed in flexible tubes orhousings 16, so as to allow the wire'to be deflected from arstraightiline either horizontally or vertically, and thus enable thewires to follow the contour of the fenders and other parts'without thenecessit of using direction-changing pulleys.

he valves on each'side of the vehicle are arranged so'that onewill openwith a for-- ward movement of its wire, and the other with a rearwardmovement of its wire, the

latter being of course connected to the re- ;spective ends of the arm14: to attain this result. A

Secured on and projecting upwardly from the cross shaft 13 adjacent thepedal 6 is a lever 17 whose upper portion 17, above the floorboard 18through which the pedal passes, is hinged to the main portion 17, as at19, in a plane at right angles to the plane of movement of the pedal andlever, so that said hinged portion may move to be in vertical alinem'entwith the main lever portion to then engage a clip 20 attached to theside of the pedal-6 or it may be disengaged from the clip and swungawayfrom the pedal to rest on the floor when the use of the sand is notrequired, as indicated in Fig. 3.

llt will therefore be evident that in operation, assuming the lever isengaged withinstallation or otherwise should demand,

a force feed of the sand, by air or others wise could be installed inconection with the system.

From the foregoing description itwill be readily seen that l haveproduced such a device as substantially fulfillsthe objects of theinvention as set forth herein.

While this specification sets forth-in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to" as do not form a departure fromthe spirit ofthe invention, as defined by the appended claims. 7 Having thusdescribed my invention what I claim as new and useful and desire tosecure by Letters Patent is:

1. A sanding device for motor vehicles comprising a sand container,pipes leading therefrom to discharge onto the tires of the wheels,closures for said pipes, a lever extending up adjacent the brake pedalof the vehicle, means conecting said lever with the closures, a hingedextension on the upper end of the lever arranged to be folded down in adirection at rightangles to the movement of the lever, and a clipprojecting from the pedaladapted to removably receive a portion of saidextension when the latter is raised.

*2. A sanding device for motor vehicles comprising sand containingmeans, pipes leading therefrom to discharge ontorthe tires of all thewheels of the vehicle, individual closure members in the pipes, andmeans for opening all said closure members simultaneously.

3. A sanding device for motor vehicles comprising sand containing means,pipes leading therefrom to discharge onto the tires of all the wheels ofthe vehicle, individual closure members in the pipes,'and means foropening all said closure members simultaneously actuated upon applyingthe brakes of the vehicle.

ln'testimony whereof ll afhx my signature.
